Water is the most important thing to survive is water. With out water you die in 3 or 4 day. Try to find the closest supermarket or a restaurant there got to be water there. If not you can drink your own pee for the first few night, but after that you can’t drink it anymore. If you can’t find fresh water you can go to a pond, a lake, or if you are a close to a sea or a ocean. You can drink the salt water, but drink very little because you can’t drink a lot at once or you can dehydrate very easy.

nice work so far Kenny! But are you sure people can drink salt water forever if they get used to it? Where did you learn that?
